Hello everyone ,
I'm having issue with my P55-C1. When pressing the power button the white led come ON , but there's no image or sound. I can see the led strips turning ON for some time and then they turn back off , this cycle goes on until I unplug the TV. I would say 15 seconds ON , 30 seconds OFF
I also noted that when the led strips are ON , there's a buzzing noise coming from the powerboard
After removing the backplate , I checked with a multimeter the voltage on the connector going from the powerboard to the mainboard , all pin label 19v had the right voltage. The DC Voltage is only present when the led strips are ON
I did a visual inspection of the mainboard or the powerboard , I didn't see any components that seemed to have failed (again , this was a very basic inspection)
Any idea to troubleshoot this further ?
Thank you
